What does chemistry bring us in terms of food, clothing, housing and transportation?

Clothing Clothing made of new synthetic fibers, soft and comfortable, cheap and durable.

The use of food and chemical fertilizers has multiplied food production; All kinds of food additives make the food colorful, flavorful.

The application of new synthetic materials makes life more comfortable.

New energy has revolutionized the means of transportation and made it easier for people to travel than ever before.

Clothing, food, housing and transportation can be separated from chemical products, except for pure cotton, linen, yarn and wool, all chemical products are made of polyester, spandex, acrylic and so on.

Chemistry is a kind of natural science, mainly at the molecular and atomic levels, studying the composition, properties, structure and change laws of matter, and creating new substances (the essence is molecules that do not exist in nature).

The world is made up of matter, and there are two main forms of change: chemical and physical changes (and nuclear reactions).

Different from particle physics and nuclear physics, which study smaller scales, the material structure of atoms, molecules, and ions (clusters) studied in chemistry interact with chemical bonds and intermolecular forces, and the scale in which they are located is the closest to the macrocosm in the microscopic world, so their natural laws are also most closely related to the physical and chemical properties of substances and materials in the macrocosm of human existence.

The word "chemistry" in Chinese, if interpreted literally, is "the science of change". Chemistry, like physics, is the basic science of natural science.

Chemistry is a natural science based on experiments. Mendeleev's periodic table of chemical elements greatly contributed to the development of chemistry. Nowadays, many people call chemistry the "central science" because chemistry is at the heart of some scientific disciplines, such as materials science, nanotechnology, biochemistry, etc.

The role of chemistry:

Clothing: Nowadays, people wear a lot of nylon and chemical fiber products. These are chemical products, such as salt, monosodium glutamate, wine, vinegar, sugar, etc.

Housing: Cement is fired from rock, steel is also reduced from iron ore, and glass is made by the reaction of ore and soda ash.

OK: The shoes we wear are made of rubber on the soles, and the inner and outer tires of the car are also rubber products. All are chemical products.

Use: Most of the items people use now are made of plastic, such as mobile phone shells, circuit boards, home appliance shells, wire sheaths, plastic plates, bowls, buckets, etc., all of which are chemical products.

Chemistry is closely related to life:

1) Plastic products at home, such as slippers, buckets, garbage bags, etc. (2) Chemical fibers for clothes, which are breathable, wear-resistant, and bright, as well as quilts, shoes, gloves, hats, socks, etc.

3) Additives in food.

preservatives antiseptic; flavors, which make food more fragrant; pigments, which make food bright; desiccant to keep food dry.

4) Materials for the manufacture of vehicles.

At present, the body and engine of the car are mostly made of alloys, and the cars of the future will be plastic, and the aircraft will use carbon fiber.

Manufacturing. 5) Life phenomena are closely related to chemistry.

The process of metabolism is essentially a process of a series of chemical changes.

This is the relationship between chemistry and food, clothing, housing and transportation.

Good luck with your studies!

This is a related question, first of all, you must be clear about the concept of chemistry, the concept of clothing, food, housing and transportation.

And then find out their intersection - cause and effect, and it will be easy to understand.

Food, clothing, housing and transportation -- it is the material embodiment of the macrocosm.

Clothes are made --- cotton thread, fiber, etc., and food -- steamed bread fermentation is made with yeast, alkaline noodles, etc.

Housing - cement, glass, paint, etc. for building houses.

Line -- Oil, electricity, etc. for transportation.

Chemistry is the science that studies the composition, structure, properties, and changes of matter. The world is made up of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world.

Chemistry can be simply understood as a change in the microscopic composition of a substance, for example: cotton thread was originally made of white cotton, but you see clothes, there are all kinds of colors, and the fibers are also refined from petroleum and then processed.

It can be said that all aspects of people's lives nowadays are related to chemistry.

Chemistry exists everywhere in life, such as washing your face in the morning with soap, facial cleanser or something, eating early and drinking milk (processing), all of which are related, and the laws of life are also very similar to the laws of chemistry, I personally think chemistry.

Chemical reactions are the driving force behind the vehicle. Without the heat emitted by the combustion of fuel, the vehicle would not be able to operate at all. Chemical energy is the most primitive energy that allows them to act**, even if electricity is used as power, the great contribution of chemical energy cannot be forgotten.

Today, chemistry is still the life of transportation and still plays a major role in people's mobility.

made of clothes, shoes made of synthetic fabrics;

Food: additives in food (artificial colors, saccharin.

etc.), preservatives (potassium sorbate.

etc.), some foods are chemical products themselves, such as wine, vinegar, bean curd; packaging buried materials, etc.;

Housing: Some of the wood boards used for the decoration of our house are bonded with organic glue (most of them contain formaldehyde analogues), and the insulation board (benzene board) of the house is also chemically synthesized;

Xing: Most of the vehicles, planes and other vehicles we travel use gasoline to generate power, which is itself a chemical change; There are also car bumpers made of polymers, and the manufacture of airplanes also requires the use of chemical organic glue.

I hope you can bend the sedan car.

What is the role of chemistry in clothing, food, housing, transportation, etc.?

Clothing: Nowadays, clothes are mainly chemical fibers, which are fibers made of natural polymers or synthetic polymers modified by chemical or physical methods. These include recycled, semi-synthetic, and synthetic fibers.

There are also silk clothes, the essence of silk is protein, and the basic component of cotton is cellulose, which are all basic chemicals, so clothing is inseparable from chemistry.

Food: Not to mention, the food we eat is all composed of chemical basic units, such as rice, flour and other basic units are mainly sugars, as well as soybean oil, lard and other mainly oils, vegetables contain cellulose, minerals, etc., meat food, mainly protein and oil, these are the basic chemical components, and in terms of food preservation, there is usually a vacuum to isolate the air, pass noble gases, low-temperature refrigeration, high-temperature sterilization, these are to slow down or eliminate chemical slow oxidation, These are all related to chemistry.

Housing: The reinforced concrete of the building materials is also a chemical material, the steel bar is iron, the basic structure of concrete is cement and yellow sand, the chemical composition of yellow sand is silica, the preparation of cement is a chemical reaction at high temperature, simply put, the brick is generated by calcination of clay at high temperature, which itself is a chemical reaction.

Line: The fuels used in our vehicles are mainly diesel, kerosene, gasoline, which are obtained from the fractionation and refining of petroleum, mainly some hydrocarbons, the combustion of fuel is a chemical reaction, and the paint on the surface of the body is also a chemical, even if you are walking, the material of your shoes is also a chemical product, glue, cloth, and soles may still be new polymeric materials.

All in all, without chemistry, the world would not be so rich and life would not be so convenient and fast!

Clothing: Many of the materials used in clothing are extracted from petroleum.

Food: fresh, preservative.

Accommodation: materials used in the decoration of the room, lacquer on the table, etc.

OK: A lot of things on the car are chemicals, like door paint.

Acrylic and other chemical fabrics.

Preservatives, formaldehyde exceeding standards, etc.

The tires are rubber.

1.Human survival is inseparable from chemistry, and chemical reactions are taking place in the human body all the time, such as food fermentation in the body, chemical reactions of various ions in the cytoplasm, etc. (Food).

2.Human life is inseparable from chemistry, such as making fire, which is the most basic and common chemical reaction. (Live).

3.Some of the fabrics used in the clothes that people wear also require chemicals, such as man-made fibers. (Clothing) 4When people are sick, they are inseparable from chemistry, such as some Western medicines, which are used to regulate the pH of the human body or stomach diseases, etc., must be completed by chemical reactions. (Medical).

1. The use of chemical fertilizers and pesticides has increased.

The yield of crops has been increased.

2. The synthesis of new drugs has saved millions of lives.

3. The development of clean and pollution-free energy will change our blue sky and clear water.

In daily life, chemistry also brings a lot of convenience to human beings, laundry detergent and soap are good products for household decontamination, beer is people's favorite drink, put some soda when steaming steamed buns, steamed buns are big, white and delicious, and there are many examples.

When it comes to food, chemistry is just as important. Use soda ash dough to make steamed buns, soft and delicious. All kinds of drinking wine are prepared by a series of chemical changes in grain and other raw materials.

Betel nut is a favorite food of ethnic minorities, and before eating, it must be soaked in slaked lime and cut into small pieces. After a certain period of time, it can be consumed.

Chemistry and medicine are also closely related, oxygen supply is the use of sodium peroxide and carbon dioxide reaction to produce oxygen, saving many lives, people also apply scientific methods to make normal saline, alleviate the pain of patients. In modern times, mankind has invented many new drugs and conquered incurable diseases, such as penicillin.

In some major scientific fields, the role of chemistry is not small, and the fuel required for rocket launch is the use of the principle of hydrogen and oxygen combustion to obtain water.

Thanks to chemistry, our houses have colorful decorations. Quicklime is soaked in water to mature lime, and the hydrated lime is coated on the top to dry into white and hard calcium carbonate, covering the yellow of the earth, and the house looks neat and bright. Chemistry makes steel, and we have iron products to use.

Chemical processing of petroleum allows us to use lightweight plastics. Chemical calcining of clay in order to make the house have a beautiful tile surface.

It is because of chemistry that we have the nylon fiber clothes we wear.

Clothing: Acrylic wool commonly used in woolen sweaters and wool jackets, the scientific name is polyacrylonitrile. Acrylonitrile is manufactured from propylene in petroleum cracking and oil refining waste gas, and after ammonia oxidation, propylene becomes acrylonitrile, which becomes polyacrylonitrile through polymerization reaction, and then becomes acrylic fiber through spinneretting and spinning.

Food: Adding some soda ash when making trowels can neutralize the acid produced during the fermentation of flour, and the carbon dioxide produced can make the bread loose and porous.

Housing: Soak quicklime in water to mature lime, slaked lime is applied to the wall and dried into white and hard calcium carbonate, which covers the yellow of the earth, making the house look neat and bright.

Clothing, food, housing and transportation can be separated from chemical products in addition to pure cotton, linen, yarn and wool, all chemical products are made of polyester, spandex, acrylic and so on: various food additives, umami - monosodium glutamate, preservatives - sodium benzoate, acidulants - citric acid, sweeteners - xylitol, etc., directly use vinegar, salt, soda, soda, soda, etc.

Residential surface: glue for house decoration, stone tabletop, glass, plastic bags, door locks, keys, etc.: the slab oil road uses mechanized asphalt paving, various vehicle shells, seats and some parts are made of plastic.

Food, clothing, shelter and transportation each give examples of advantages and disadvantages.

Eating, wearing, and using things abound.

Food, clothing, housing, and transportation all cite pros and cons.
